Chlorpyrifos (Cat No.: R007094) is a broad-spectrum organophosphate insecticide widely used in agriculture to control pests on crops such as corn, soybeans, and fruit trees. It works by inhibiting acetylcholinesterase, an essential enzyme for nervous system function, leading to paralysis and death in insects. Despite its effectiveness, chlorpyrifos has raised health and environmental concerns due to its neurotoxic effects, particularly in children. As a result, its use has been banned or restricted in several countries and is under increasing regulatory scrutiny worldwide.
